The Burying Beetle made the Branford Boase Award shortlist and The Bower Bird was Costa Children's Book of the Year.
The Burying Beetle and The Bower Bird chronicle the story of Gussie, a 12-year-old girl who suffers from pulmonary atresia, a rare heart disease.
The character is modelled on Ann's late son, Nathan Kelley, who suffered from the same congenital heart condition.
It's a glimpse into the head of a child with a chronic disease, who has to find a way to live her short life to the full... Gussie isn't my son.
She is an honorary teaching fellow at Peninsula College of Medicine and Dentistry, University of Exeter and Plymouth.
